How credits work
Credits are bought per project in the developer portal at $0.01 each (sales tax may apply), and each generation consumes credits by model: per second of output for video, per image for images. Dollar figures below are credits times $0.01.

Runway also hosts Google's Veo 3.1, which Google removed from its own Gemini API; see Veo pricing.
Image models

Limits that affect cost
Runway's models page lists duration and resolution limits for many models, for example Kling 3.0 Standard and Pro at 3 to 15 seconds, Wan 3.0 at 2 to 30 seconds and 480p to 1080p, Seedance 2.5 up to 30 seconds and up to 4K, and Kling 4.0 at 3 to 30 seconds. A longer or higher-resolution clip costs proportionally more credits, so check the limits before budgeting a long clip.
Other services in the same credits
The page also prices audio models (for example ElevenLabs voices and sound effects), upscalers and real-time avatars in credits. For speech and voice costs see ElevenLabs pricing.
